Recent Development of Novel Superconductive Materials

The progresses in the research of copper oxide high T_c superconductor (HTS) are reviewed systematically, and the modified methods of cupper oxide HTS are introduced in detail. Also, the recent development on MgB_2 superconductor and organic superconductor is presented. Especially, the structure and properties of MgB_2 superconductor are emphasized. In addition, a new kind of superconductor CoO_2 is listed.
